i l 'srnnnnswnnrm To all whom t may concern.'

Be it known that l, CLAuDIUs SIMON, a citizen of the United States,residin at Casco, in the county of Kewaunee and tate of Wisconsin, haveinvented new and useful Improvements in Street-Sweepers,`of which thefollowing is a s ecification.

This invention re ates to street sweepers and it consists in the novelfeatures hereinafter described and claimed.

An object of the invention is to improve a street sweeper in point ofsimplicity, durability and eciency and partlcularly to provide new andimproved means for ele'- vating the brushes of the sweeper in order thatthe machine may be readily turned or moved over the surface of apavement without disconnecting the operating means for h brushes andthus causing unnecessary e ay.

The invention also includes other features hereinafter described andmore particularly pointed out in the claims.

ln the accompanying drawings Figure 1 is a side elevation of streetsweeper;

Fig. 2 is a top plan view of the same;

Fig. 3 is a longitudinal sectional View of the same;

Fig. 4 is a fragmentary sectional view of the same cut on the line 1-4of Fig. 5;

Fig. 5 is a fragmentary plan view of parts shown in Fig. 4f;

Fig. 6 is a transverse sectional view of the same cut on the line 6 6 ofFig. 1;

Fig. 7 is a similar view cut on the line 7 7 of Fig. 1;

8 is a transverse fragmentary sectional view of the same cut on the line8--8 of Fig. 1.

The street sweeper comprises a frame 1 of suitable structure which ismounted at its rear portion upon an axle 2, there being wheels 3journaled for rotation at the ends of the said axle. The forward portionof the frame 1 is supported upon a truck a in the usual manner. Anoperators seat 5 is mounted u on the forward portion of the frame 1.hopper 6 is mounted upon the rear portion of the frame 1 and is providedat its rear end with a hin ed gate 7.

A shaft 8 is journaled or rotation at the upper portion of the hopper 6and a sprocket wheel 9 is loosely mounted thereon. A sprocket wheel 10is attached to one of the wheels 3 and a sprocket chain 11 is trainedspeciaals-tion' of Letters recent.

around the'wheels 9 and 10 and is adapted to transmit rotary movementfrom one of the wheels 3 tothe said sprocket wheel 9. A clutch member 12 is slidably mounted upon the shaft 8 but is restrained to rotate inunison therewith and a sprin 13 bears at one end against the clutch memer 12 and at its other end against the side of `the hopper 6 and isunder tension with a tendency to normallyhold the clutch member 12toward the wheel 9 as best shown in Fig. 8 of the drawing. When theclutch member 12 is in engagement with the hub of the wheel 9 the shaft8 rotates in unison with the wheel 9. Bearings 14 are mounted at theside of the hopper 6 and a rod 15 is journaled in the said bearings.lThe rod 15 is provided at its upper end with an angularly disposed crank16 which engages the clutch` member 12. The rod 15 is provided' at itslower end with an angularly disposed crank 17. A lever 18 is pivotedupon the forward portion of the frame 1 in the vicinity of the operatorsseat 5 and any usual or suitable means may be provided for holding thesaid lever 18 at an adjusted position.

yA rod 19 operatively connects the lever 18 with the crank 17. Hence itwill be seen that when the lever 18 is swung in one direction the rod 19is moved longitudinally whereby the rod 15 is turned in the bearings 14and the crank 16 will carry the clutch member 12 out of engagement withthe hub of the sprocket wheel 9. When the lever 18 is moved in anopposite direction the said clutch member is moved into engagement withthe wheel 9 and is securely held in such engagement under the influenceof the spring 13.

'A trough 20 is pivotally connected with the upper forward portion ofthe hopper 6 by means of arms 21 and the said trough is provided at theupper edges of its sides with inturned flanges 22. Bars 23 are pivotallyconnected with the lower forward end of the trough 21 and are providedwith upstanding lugs 2/1. Bolts 25 are pivotally connected at their rearends with the lower forward portion of the trough 20 and passtransversely through the lugs 24. Nuts 26 are screw-threaded upon theforward portions of the bolts 25 and coil springs 27 bear at theirforward ends against the nuts 26 and at their rear ends against the lugs211. The springs 27 are under tension with a tendency to normally holdthe forward ends 'of the bars 23 down, although the said bars may movein an upward direction when they are subjected to sufficient force orpressure to compress the springs 27.

A roller 28 is journaled for rotation between the bars 23 at the forwardends there. of and a roller 29 is journaled for rotation at the lowerforward portion of the trough 20. Sprocket wheels 30 are mounted ugonthe shaft 3 and sprocket chains 3l are trained over the sprocket wheels30 and around the roller 28. rlhe lower runs of the chains 3l aretrained under the roller 29.` rhe chains 31 carry brushes 32, the endsof the bodies of which are adapted to move under the \f1anges 22hereinbefore described and as best illustrated in Fig. 3 of the drawing.A drum 33 is journaled for rotation upon the forward portion of theframe l and is provided with ratcheiJ wheels 34. Spring pressed pawls 35are -pivotally mounted upon the frame l and engage the ratchet wheels3Q: and serve to prevent the drum 33 from rotating in one direction.rlhe shaft of the drum 33 may be provided with a crank handle 36 whichmay be used for turning the drum 33 in an opposite direction. yCables3'? are arranged to wind upon the drum 33 and the said cables pass overa roller 38 iournaled upon the frame l and are connected at their rearends with the lower forward portion of the trough 20. By winding thecables 37 upon the drum 33 the slack may be taken out of the said cablesand the lower forward portion of the troug 20 may be supported at adesired elevation with relation to the surface of the street orpavement. Shafts 39 are pivoted upon the frame l at points between thedrum 33 and the roller 33, and the said shafts are provided at one endwith angularly disposed hooks Ll() which engage over theV cables 37. Theshafts 39 are provided at their other ends with cranks el which aredownwardly disposed. A shaft d2 is pivoted upon the frame l at a pointin advance of the operators seat 5 and is provided with an upstandingpedal e3. rlhe shaft 4t2 is pro vided at its ends with downwardlydisposed cranks 4A. Rods 45 are connected at their forward ends with thecranks t and at their rear ends with the cranks lll.

rThus it will be seen that when the operator places his foot upon thepedal 43 and depresses the same whereby the shaft 42 is turned, thecranks ed are swung about the axis of the shaft 42 and the rods Zl5 aremoved longitudinally. These in turn, through the cranks el, swing theshafts 39 whereby the hooks 40 will mediate portions of the cables 37and hence the forward portion of the trough v20 may be temporarilyraised above its normal position with relation to the surface of thestreet or roadway.

lt is of course, understood that when the shaft t2 is manipulated asbest described the brushes may remain in movement along the trough 2Oand when the forward portion of the .said trough is temporarily raisedthe machine may be turned around or carried over obstructions at thesurface of the street or road. v

From the foregoing description taken in conjunction with theaccompanying drawing, it will be seen that a street sweeper of imple anddurable structure is provided and that the same may be easily andquickly manipulated to overcome obstructions and to facilitate theturning of the same.

Having described the invention what is claimed is l. A street sweepercomprising a frame, a hopper mounted thereon, a trough pivotallyconnected with the hopper, brushes mounted for movement along thetrough, means for moving the brushes, a drum journaled upon the frame,cables arranged to wind upon the drum and connected with the trough, andmanually operable means for distorting the cables to raise the forwardportion of the trough.

2. A street sweeper comprising a frame, a hopper mounted thereon, atrough pivotall f connected with the hopper, brushes mounted formovement along the trough, means for moving the brushes, a drumjournaled upon the frame, a roller journaled on the frame, cablesarranged to wind upon the drum and trained over the roller and connectedwith the trough, shafts journaled upon the frame and having hooks whichengage over the said cables and manually operable means connected withthe shafts and adapted when manipulated to distort the cables wherebythe trough is raised.

3. A street sweeper comprising a frame, a trough mounted thereon, barspivotally connected to the trough, brushes mounted for movement alongthe trough and the said bars, lugs carried by the bars,l bolts pivotallyconnected with the trough and passing through the lugs and springscarried by the bolts and bearing against said lugs.
